Roche, Eli Lilly’s Alzheimer’s blood test gets FDA clearance

HealthRoche, Eli Lilly's Alzheimer's blood test gets FDA clearanceBy Reuters -Aug 25, 2026Add ARY News on GoogleRoche, Eli Lilly's Alzheimer's blood test gets FDA clearanceAAResizeThe U.S. Food and Drug Administration has cleared Roche and partner Eli Lilly’s blood test to help ​identify signs of Alzheimer’s disease in people aged ‌55 and older with cognitive decline. The test, Elecsys pTau217, is a biomarker blood test that can help doctors identify patients who are ​likely or unlikely to have Alzheimer’s-related brain changes, ​Roche said on Monday. The test can be ​run on more than 4,500 Roche laboratory analyzers already installed ​across the United States, which the company said could help broaden access. Separately, Labcorp and Quest Diagnostics said that they plan to offer ​the test through their laboratory networks, potentially expanding availability ​across the United States. Roche did not disclose the test’s price. Current methods to ‌detect ⁠amyloid, a protein linked to the disease, typically rely on positron emission tomography or PET scans or cerebrospinal fluid testing, which can be expensive, invasive and less widely ​available. The FDA clearance ​comes as ⁠drugmakers and diagnostic companies race to develop simpler tests for Alzheimer’s disease amid growing ​demand for earlier diagnosis and treatment. Fujirebio’s Lumipulse became ​the ⁠first blood test cleared by the FDA to aid in the assessment of Alzheimer’s disease in 2025. Elecsys pTau217 is not ⁠intended ​to be used as a standalone ​diagnostic test and results should be interpreted alongside other clinical information, Roche ​said.
